Last week we held 2-day (on November 10th and 11th) technical writing sprint.
The goal was to write some of the missing technical documentation for the Tinusaur project and more specifically the guide how to assemble your Tinusaur Board. 14 people participated – THANKS A LOT for helping us!
The documentation is not quite finished yet but it was a good start.
The final version will be available at tinusaur.github.io.
We would like to have the guides and the tutorials copied from the Tinusaur GitHub repository over to this blog here that is hosted at WordPress.com. Any suggestions how to do it more efficiently (without copying and pasting files and content from one website to another) will be really appreciated.

This Saturday, September 2nd, we will have one day workshop for assembling the Tinusaur kits for those who supported our Indiegogo crowdfunding campaign. It will take place in Varna, Bulgaria, our host will be VarnaLab – the local hackerspace.
We will bring to the workshop soldering irons and all the necessary materials to do the job. Also, for those who were not able to get one of the kits during our Indiegogo campaign, we will have some for sale.
At the moment we can organize such workshops only in Bulgaria but we’d really like to start doing this in other countries. Volunteers are very welcome. 🙂

If you’re around, you’re welcome to come.
The first day we assembled some boards, the second day we wrote some programs.
For the younger kids, there were much simpler things to do – soldering blinking LED with 2 transistors, few other components, and a battery.
Just assembling various boards.
It wasn’t difficult for anyone to do that. There are markings on the PCB that tell you where to put each component and in what direction.
The only important thing to know is that you solder the RESET button last, before that you solder the batter socket on the bottom side of the PCB.
Tinusaur Shield LEDx2
This shield is an upgrade from the previous Tinusaur Starter where we had to solder the LED and the resistor to a tiny 2-pin male header. With the shield is so much easier and fun.
LED Matrix 8×8 with MAX7219 Controller
This is a LED matrix 8×8 with a MAX7219 controller.
Even while we’re soldering it people were coming with ideas what we could do with it.
The second day was dedicated to programming what we’ve assembled the previous day.
Software and Arduino IDE Setup
That’s how we started the day 2.
The “Hello, World!” in the microcontrollers’ world.
Source code available at https://bitbucket.org/tinusaur/tutorials/src/default/tut004a_blinking_leds/.
Separate blog post and tutorial page will be available soon.
LED Matrix 8×8
The biggest challenge here was to make the MAX7219LED8x8 library to work in the Arduino IDE environment.
We’ll do another post about that in the next few days.
This time, it was for 2 days and in 3 parts.
Part 1 (day 1) was an introduction to the microcontrollers for everyone that was just starting – short 30 minutes presentation and then discussions about various problems that one may experience while working with input/output. It was interesting to see some observation by people that have no much experienced about buttons and the noise that they may produce, then … how do we do debouncing.
One of my friends shot a timelapse at one of the tables.
Part 3 (day 2) was the fun part.
We wrote the blinking LED program – that was easy.
Then we started experimenting.
We also managed to play polyphonic tunes using ELM – Wavetable Melody Generator.
But the most unusual thing we did was to make an old floppy disk drive play a melody.
Oh, by the way, incase you’ve not heard it yet 🙂 …
The second Tinusaur workshop took place last Saturday (on the 14th of February) in the Veliko Turnovo – University “St. St. Cyril and Methodius”.
The youngest were 2 children – 8 and 11 years old. 🙂
The The First Tinusaur Workshop was exactly 2 month ago.
The first official Tinusaur workshop took place last Sunday (on the 14th of December) in the Veliko Turnovo University “St. St. Cyril and Methodius”. It was really great!
The workshop was attended by 22 people of age 16 to 44.
As you may have guessed already it was for the absolute beginners so we first learned how to solder basic things like resistors, capacitors and other small parts. Then we move to soldering The Tinusair Board.
Not all people who wanted could attend the even so we may organize another one in the first months of the next year.
